CAP AND LOCKING `DEVICE FOR CLOSING PIPES OR'ORIFICES.

SPECIFICATION forming part of Letters PatentlNO. 518,008, datedrAprl 10,1894. Application led December 13, 1893. lSerial No. 493.527. (Nomodel.)

To all whom tm/tty concern..-

Be it known that I, JOSEPH RILING, a citizen of the United States,residing at Philadelphia, county of Philadelphia, and State ofPennsylvania, have invented a new and useful Improved Cap and LockingDevice for Closing Pipes or Oriiices', of which the following is a full,clear, and exact description, reference being had to the accompanyingdrawings, Which form a part of this specification.

My invention has for its objectv to close orifices in cans, barrels, orother devices, or ends of pipes, so that they can be opened only bymeans of a key of particular character and. thus access to lthe interiorof the can, barrel or pipe cannot be had Without the use of this key. Inthe drawings I have illustrated my device -as applied to a can, the usebeing to close and lock the orifice through which the liquid is pouredinto the can,and as closing the end of a pipe.

In the drawings-Figure 1 is a perspective view partially in vsection ofa can with my device applied. Fig. 2 is a sectional view of la pipe theend of which is closed by my device. Fig. 3 is a plan view of the capand locking device. Fig. 4 is a plan view of casing. Fig. 51is aperspective viewr of the key. Fig. 6 is a perspective view of the capand pipe dispensing with the case.

Describing generally, A is the casing provided with the exterior threadsa. and interior threads aand the interior Iiange a2.

B is the cap which is preferably cylindrical in shape and havingthreads, b, on its exterior.

One end, b', of the cap is ixedly secured toV the sides, and the otherend b2 is secured so as to have a movement vertically and to rotate. Astandard b3 is secured to the end b and extends through an orifice b4 inthe end b2. Around this standard, b3, is the coil spring, b5. A iiangebe confines the movement of the end, b2, in one direction. In the end,bis the orifice, 197, through which the hasp, c, of the key, O, isadapted to pass. The key O has in its hasp an inset, o', of any desiredform, andn upon the end, b', is an 4inset with which the key is adaptedt0 register. The casing is inserted either in the orifice in thecan orbarrel, or in the end of the pipe and the cap placed in the casing. Thekey O is .then used, the orifice, o2, registering with the standard b3and the hasp c passing through the orifice, o7. By means of the key, theend, b2 is forced down until the hasp of the key is in contact with theend b when the key is turned, turning only the end, b2, until the'vkeyregisters with its corresponding cut in the end, b', when the entire capis rotated, which screws the cap 6o into the casing until the capreaches a point in line with or slightly below the other end of thecasing. The key is -then removed, the opening into thecan or barrel orthe end of the pipe is then closed, and closed in such manner that itWill require the use of the same or a similar key to remove the cap.Wherethe device is used on cans itis advisable to use the case, as inthat case there should be a portion projecting outwardly beyond the wall7o .i

of the can, the case being used for this purpose as it is useful infilling the can, But where the cap is used merely to securely close anopening, as the end of a pipe, so as to prevent tampering, in that caseit is only necessary 7 that the cap should be used and the walls of theorifice threaded so as to receive the threads upon the cap, and the capshould be threaded to such an extent that the cap, Where screwed to itsfull extent, is on a level with or within 8o the outer'line of the pipeor other device the opening in which is to be closed.

My device is very useful in those cases Where the cans are the propertyof the party serving or providing the liquid, such, for instance, asoil, 4and the consumer agrees to purchase the supply from' him. With theuse of this device the supplier could, by retaining the key, prevent thecan being filled by others than himself. 9o Having now fully describedmy invention," what I claim, and desire to protect by Letters v l. A capprovided ywith a threaded exterior, a fixed end and an end adapted tomove vertically independently of the fixed end, said last mentioned endbeing provided with an orifice for the insertion of the key; and the xedend being provided with a device adapted to register with the key.

2. A cap provided with a threaded exterior, a xed end and an end adaptedto rotate independently of the fixed end, said last mentioned end beingprovided with an orifice for the insertion of the key, and the fixed endbeing provided with a device adapted to register with the key.

3. A cap provided with a threaded exterior, a xed end, and an endadapted to rotate and move vertically independently of the fixed end,said last mentioned end being provided with an orice for the insertionof the key, and the fixed end being provided with a device adapted toregister with the key.

4. A cap provided with a threaded exterior, a xed end and an end adaptedto rotate and move vertically independently of the xed end, said lastmentioned end being provided with an orifice for the insertion of thekey, and the iixed end being provided with a device adapted to registerwith the key, and a spring between said ends.

5. A cap provided With a threaded exterior, a fixed end and an endadapted to rotate and move vertically independently of the xed end, saidlast mentioned end being provided With an orifice for the insertion ofthe key and the fixed end being provided with a device adapted toregister With the key, a standard secured to the xed end and passingthrough the movable end and adapted to receive the orifice in the key.

6. A cap provided with a threaded exterior, a xed end, and an endadapted to rotate and move vertically independently of the fixed end,said last mentioned end being provided with an orifice for the insertionof the key, and the fixed end being provided With a device adapted toregister with the key, a spring between said ends, a standard secured tothe fixed end and passing through the movable end and adapted to receivethe orice in the key.

In testimony of which invention I have hereunto set my hand.

JOSEPH RILING.
